Install The Air Line Accessories; Install The Fluid Line Accessories; Install The Gun And Mounting Bracket - Graco 236685 Instructions And Parts List

Install the Air Line Accessories

1. Install a bleed-type master air valve (X) on the
main air supply line (W) to shut off all the air to the
gun. See Fig. 1, page 8.
2. To ensure a dry, clean air supply to the gun, install
an air line filter and an air and water separator on
the air lines. Dirt and moisture can ruin the appear-
ance of your finished workpiece and can cause the
gun to malfunction.
3. Install an air regulator (M) on each of the air supply
lines (B, C, D, E, Y) to control the air pressure to
the gun.
4. Install a solenoid valve (K) on the fan and atomiza-
tion air lines (C, D) to actuate the gun and shut off
the fan and atomization air to the gun. The sole-
noid valves must have a quick exhaust port.
WARNING
PRESSURIZED EQUIPMENT HAZARD
Trapped air can cause the gun to spray
unexpectedly, which could result in a
serious injury, including splashing in the
eyes or on the skin. The solenoid valves (K) must
have a quick-exhaust port so trapped air will be
relieved between the valve and the gun when the
solenoids are shut off.

Install the Fluid Line Accessories

1. Install a fluid filter and drain valve at the pump
outlet. See Fig. 1, page 8.
WARNING
PRESSURIZED EQUIPMENT HAZARD
The fluid drain valve is required in your system to
assist in relieving fluid pressure in the displacement
pump, hose and gun; triggering the gun to relieve
pressure may not be sufficient. Install a drain valve
close to the pump's fluid outlet. The drain valve
reduces the risk of serious injury, including splash-
ing in the eyes or on the skin.

2. Install a fluid regulator on the fluid line to control
fluid pressure to the gun.

Install the Gun and Mounting Bracket

1. Loosen the mounting bracket's two square head
bolts (103) and slide the mounting bracket onto a
0.50 in. (12.7 mm) mounting rod. See Fig. 3.
